2. Configuration


Earth system components included in the analysis system

(e.g., ocean, sea-ice, land, etc.)

Assimilated and Interactive Aerosols. Observation-based precipitation driving the land surface and aerosol wet deposition except in the high latitudes (Reichle et al. 2017a).

Horizontal resolution of the model, with indication of grid spacing in km

(for the different Earth system component included in the model)

The model is run on a cubed sphere grid. Data are provided at 0.625° longitude by 0.5° latitude  (576 by 361 grid points, approximately 50kmby 50km).

Number of levels in the different Earth system components

(for the different Earth system component included in the model)

72 native model levels, also interpolated to 42 pressure levels.
Frequency of the outputs2D variables at 1 hourly frequency, 3D variables at 3 hourly frequency, Analysis variables at 6-hourly frequency.
